aight the title tells all, but for the most part heres a general description of the setup. 97gsr head LS block OBD 2> OBD1 conversion. (gsr wiring harness) P28 ECU and it was converted from auto > manual.... not that it really matters but anyways heres the deal... 3 things wrong. 1. It keeps throwing code 1. (primary o2 Sensor) The sensor itself is good, and plugged in but still throws the code and we cant figure out why. 2. My p28 ecu's rev limit seems to be set to 4k and it cuts out.. gets to 4k and then nada. We threw in a stock obd1 gsr ecu and it revved fine.. Could the ecu just need a re-program? or a new basemap to go on possibly? 3. The throttle cable wont seem to give us enough slack, Im using a skunk2 intake mani (the one that looks similar to the C5 intake mani) and the bracket needed to be bent a bit to get it to meet but the damn thing still doesnt have enough slack so it holds idle @ 2k lol, anyone ever mickey mouse any of this shit?!?!?! Thanks in advance, its my first swap and it hasnt been a smooth ride..
